Crate aither_copilot 

GitHub Copilot integration for the Aither framework.

This crate provides a Copilot client that implements the LanguageModel trait, allowing you to use GitHub Copilot’s chat API through the unified aither interface.

GitHub Copilot uses OAuth device flow for authentication. The typical flow is:

1. Call auth::request_device_code to get a device code and verification URL
2. Direct the user to the verification URL to enter the code
3. Call auth::poll_for_token to wait for the user to complete authentication
4. Use the token to create a Copilot client

use aither_copilot::{Copilot, auth};
use aither_core::LanguageModel;

// Request device code
let device_code = auth::request_device_code().await?;
println!("Visit {} and enter code: {}", device_code.verification_uri, device_code.user_code);

// Poll for token
let token = auth::poll_for_token(&device_code.device_code, device_code.interval).await?;

// Create client
let copilot = Copilot::new(token.access_token);
